3. XRootD.client.CopyProcess: Copying files

3.1. Class Reference

class XRootD.client.CopyProcess

Add multiple individually-configurable copy jobs to a “copy process” and run them in parallel (yes, in parallel, because xrootd isn’t limited by the GIL.

3.1.1. Methods

CopyProcess.add_job(source, target, sourcelimit=1, force=False, posc=False, coerce=False, thirdparty=False, checksumprint=False, chunksize=4194304, parallelchunks=8)

Add a job to the copy process.

Parameters:

• source (string) – original source URL
• target (string) – target directory or file
• sourcelimit (integer) – max number of download sources
• force (boolean) – overwrite target if it exists
• posc (boolean) – persist on successful close
• coerce (boolean) – ignore file usage rules, i.e. apply FORCE flag to open()
• thirdparty (boolean) – do third party copy if possible
• checksumprint (boolean) – print checksum after the transfer
• chunksize (integer) – chunk size for remote transfers
• parallelchunks (integer) – number of chunks that should be requested in parallel
